lisa stark joins us from washington. what is the latest? >> that train should have been going at 30 miles an hour around the curve. there are no published reports this morning including from wabc, those reports indicate that the engineer, william rockefeller has said he may have zoned out at the controls. he may have dosed off and then snapped awake too late to stop the train in time the ntsb will continue to interview the engineer and also look back at the man's 72-hour history before this accident. did he get enough sleep? did fatigue play a roll in this accident. the train left his original station very, very early sunday morning. fatigue has long been a concern in transportation accidents, and that will certainly be one of the key questions here. >> and that really gets to the heart of whether this was mechanical failure on human error. thank you lisa. >>> up next a look at today's top headlines and a rundown on some nasty weather on the horizon. >>> welcome back to al jazeera america. i'm stephanie sy. here are today's head loins. pres
